By three-dimensional knit fabric of the present invention and the core and the layered product that comprise three-dimensional knit fabric are used for air cleaner, liquid filter especially for papermaker's felt, for example having the press for extracting juice water-based that can make papermaker's felt increases substantially, compress restorative, compressed residual strain rate and diminish the effect of practical excellent in te pins of durability.
The specific embodiment
Carry out following specifying for the present invention.
Three-dimensional knit fabric of the present invention is to use braidings such as double-needle bed raschel braiding machine with two row pins row, Double Circle knitting machine to form.Braid can use mesh braid, leno-marquisette braid etc. to have the braid of a plurality of opening portions in the table, especially, because the surperficial convex-concave that sley bar tissue and Queens Cord organize diminishes preferably.Braid can be identical knit stitches in the table, also can be different knit stitches.
This three-dimensional knit fabric is to link the binding yarn weaving that the monofilament of braid in this table makes by the yarn that constitutes braid in the table and being used to form, and the binding yarn preferably uses the synthetic fiber monofilament of monofilament fineness as 15dtex～1000dtex.More preferably 50dtex～400dtex, the fineness of 100dtex～300dtex most preferably.
There is no particular limitation to use the kind of monofilament, can use the monofilament of being made by synthetic resin such as polyesters that can melt spinning, polyamide-based, polypropylene type, polyethylene kinds.Cross sectional shape can use polygonal, leafy shape, hollow shape and unsetting such as circle, the triangle as abnormity, L shaped, T shape, Y shape, W shape, quatrefoil, octofoil, pancake, dumb-bell shape, the circular section shape that preferred tensile strength is bigger.By using the monofilament of synthetic fiber, can reduce since repeatedly the thickness that causes of compression reduce, as layered product under situation about for example using as papermaker's felt, can significantly prevent to press the minimizing of water-based.When linking yarn and use monofilament fineness less than the monofilament of 15dtex, or when directly using multifilament, three-dimensional knit fabric is poor through the retentivity of compressed thickness repeatedly.During as the monofilament more than the connecting fiber use 1000dtex, because the flexural rigidity of monofilament is excessive, it is very difficult, not preferred that the braiding of three-dimensional knit fabric becomes.
Such monofilament can use air cooling or water-cooled monofilament manufacture method to make by known melt spinning.
The fiber that constitutes braid in the table of three-dimensional knit fabric can use by common synthetic resin fiber, regenerated fiber and the natural fabric etc. made that can melt spinning.The kind that constitutes fiber is not particularly limited, can use by can melt spinning, can dry spinning or the synthetic fiber made of polyesters that can the wet type spinning, polyamide-based, polypropylene nitrile, polypropylene type, polyethylene kind, aromatic polyamide, polyketone class, polyphenylene sulfide ethers, polyether-ether-ketone resinoid.In addition, the cross sectional shape of fiber can use polygonal, leafy shape, hollow shape or unsetting such as circle, triangle, L shaped, T shape, Y shape, W shape, quatrefoil, octofoil, pancake, dumb-bell shape.The fibre fineness of braid is preferably 0.1dtex～300dtex for three-dimensional knit fabric in the formation table.Monofilament fineness is 10～300dtex more preferably, is more preferably the above monofilament of 20dtex, only most preferably comprises braid in the table that is made of monofilament and links the three-dimensional knit fabric of yarn.When braid uses the following multifilament of 0.1dtex in the table, since with staple fibre through needle point method with as the three-dimensional knit fabric of core when integrated, the silk of braid is cut off by pin in the formation three-dimensional knit fabric table, this cut-off parts becomes the collapsed mode of concavity, as the poor durability of layered product, therefore not preferred.
Constitute when the fiber of braid uses fineness to surpass the monofilament of 300dtex in showing,, be very difficult to weave into three-dimensional knit fabric because the flexural rigidity of monofilament is excessive.
Three-dimensional knit fabric of the present invention is especially when using as the layered product behind the lamination up and down, the fiber of braid is by using the above monofilament of 10dtex in the table of formation three-dimensional knit fabric, can prevent particularly through needle point method interweave and integrated operation in the cut-out of fiber, do not reduce as the intensity of three-dimensional knit fabric and preferred.
The three-dimensional knit fabric that the binding yarn weaving of making at the monofilament that is linked braid in this table by the yarn that constitutes braid in the table and being used for forms need make one maximum area in the countless spaces of the single face at least of braid in the table at 0.1mm
2～6.0mm
2Scope in.At least single face space is less than 0.1mm
2The time, the air of layered product or the permeability of liquid are poor, and consequently filterability reduces.And, surpass 6.0mm in maximum area
2The time, the variation that interweaves with nonwoven fabric of lamination up and down etc., even simultaneously owing to its void shape behind lamination is still residual, when for example using as the paper grade (stock) layered product, not preferred because the pattern of dehydration back three-dimensional knit fabric is transferred on the l Water Paper, become the fold and the damage reasons that produce l Water Paper sometimes.
Three-dimensional knit fabric can be used as with the other materials lamination in the core that uses use.As the other materials of lamination, can use nonwoven fabric, cotton, paper shape thing.As the material of other materials, by at least a the making in synthetic fiber, regenerated fiber, natural fabric, the paper pulp, can use by monofilament fineness is the nonwoven cloth-like thing (hereinafter referred to as felt) that the staple fibre of 0.01～25dtex is made.The fineness that constitutes the fibrous material of felt is during less than 0.01dtex, and the compression of felt is restorative poor, and when using as felt, the reduction of thickness is bigger, and the pressure loss also becomes greatly, the filter efficiency variation.And when 25dtex was above, the density refractory of nonwoven fabric consequently can not obtain the abundant efficient as filtering material to improve.The cross sectional shape that constitutes fiber can use polygonal, leafy shape, hollow shape or unsetting such as circle, triangle, L shaped, T shape, Y shape, W shape, quatrefoil, octofoil, pancake, dumb-bell shape.
The basic weight of felt is preferably 10～2000g/m
215g/m more preferably
2More than.The felt that uses can be according to determining that purposes suits.
The core that constitutes by three-dimensional knit fabric and can it be interweaved by known needle point method or columnar flow at the felt of lamination up and down.
Needle point method is meant and utilizes pin to carry out mechanical interweaving method, carries out lamination with felt with by the core that three-dimensional knit fabric constitutes, and by using needing machine it is interweaved with integrated.The target that interweaves is that pin density is preferably 5～50 times/cm
2, also can change according to the fibrous material that uses.
Utilize interweaving of columnar flow to use known spun-laced machine, water under high pressure is sprayed with column from pore, utilize waterpower to carry out interweaving method up and down.The degree that interweaves is advisable so that felt up and down and three-dimensional knit fabric are peeled off.
Effective through interweaving of needing machine for monofilament fineness felt big, 1～25dtex, it is useful as liquid filter, relative therewith, the felt little for monofilament fineness, 0.01～1dtex that interweaves that uses columnar flow is effectively, and is effective for air cleaner.
Three-dimensional knit fabric preferred liquid when using as the core of liquid filter, for example the seepage velocity of water is 1～10ml/cm
2Second.When the seepage velocity of water is 1ml/cm
2Second, filter efficiency and press for extracting juice water-based were poor when following.And, felt and three-dimensional knit fabric are being difficult to tufting in incorporate operations such as acupunctures.And when the seepage velocity of water at 10ml/cm
2When second above, when layered product uses as filter, filter efficiency variation and not preferred.
When using as the core of air cleaner, preferred loss of air pressur is below the 300Pa.Loss of air pressur when 300Pa is above, the fluid that makes filtration by the time necessity can quantitative change big, need the macro-energy fan simultaneously and not preferred.In addition, have owing to stop up the shortcoming of the lost of life that makes filter.
Layered product for example can be used as air cleaner base material, liquid filtering modulator material, particularly uses with base material as paper grade (stock) felt.
The thickness that is used for the three-dimensional knit fabric of papermaker's felt as layered product is not particularly limited, from the scope of the preferably about 1.5mm of angle～about 6mm of pressing water-based and durability.Here said press for extracting juice water-based is meant uses layered product to dewater from up and down moistening paper wood being exerted pressure.
The seepage velocity of the water of three-dimensional knit fabric used herein and layered product that three-dimensional knit fabric is used as core is preferably 0.4～2.0ml/cm
2Second.The seepage velocity of water is at 0.4ml/cm
2Second is when following, so press for extracting juice water-based difference is not preferred.The seepage velocity of water surpasses 2.0ml/cm
2Second the time, filter efficiency variation when using, the pattern emersion of the core of Shi Yonging and not preferred sometimes as filter.
In addition, layered product can be used as the air cleaner use.
When as air cleaner, airborne particulate filters and keeps the filter efficiency and the pressure loss is very important, for example utilizing the nonwoven fabric manufacture method of meltblown or spun-bond process, dry method etc. can use monofilament fineness is the fiber of 0.01～25dtex, is preferably 0.02～1dtex.With the lamination of three-dimensional knit fabric, the known spun-laced machine of use that interweaves, the basic weight of preferred felt is about 20～about 200g/m
2, the upper and lower surface of three-dimensional knit fabric can use identical or different felt.As layered product, the preferred pressure loss is for below the 300Pa.And the arresting efficiency to the particle of 0.1～5.0 μ m is more than 80%.
The pressure loss and particle trapping efficient can use known method (for example, Japanese kokai publication hei 07-100315 number) to measure.
